Remove request ".br" if it precedes a line, that begins with a
space, as such lines automatically cause a break.

These links were mostly created when pages were moved between
sections, in almost every case several years ago. The idea
was to allow people time to get used to the new section numbers
while still having commands of the form "man <sec> <page>"
work as before. Let's assume that people have now had time to
get used to the new section numbers, and remove these links.

These are all links that were created several years ago, mainly
when pages were migrated to different sections, in order to
allow the 'man' commands using the old section numbers to work.
However, the plan was always to eventually remove them, after
allowing people who cared to get used to the new section numbers.
Now, after 5+ years in each case, it's time to remove
these links.

I believe new users should be discouraged from using atoi() and
that its disadvantages should be explained.
I added the information that 0 is returned on error - although C
standard and POSIX say that "If the value of the result cannot be
represented, the behavior is undefined." there are some
interpretations that 0 has to be returned
https://stackoverflow.com/questions/38393162/what-can-i-assume-about-the-behaviour-of-atoi-on-error
and this is also what happens in practice with glibc, musl and
uClibc.

Starting with Linux 5.8, setns() can take a PID file descriptor as
an argument, and move the caller into or more of the namespaces of
the thread referred to by that descriptor.
Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>
The page currently incorrectly says that 'fd' must refer to
a descendant PID namespace. However, 'fd' can also refer to
the caller's current PID namespace. Verified by experiment,
and also comments in kernel/pid_namespace.c (Linux 5.8-rc1).
